e Specification of certain Improvements. in Blind-Fasteners, invented by JOHN A. PIPQ and WILLIAM WAL. BAUM,'hoth of. Hoboken, inthe county f Hudson, and State of New Jersey. l

` `Nature and Object of the Invention. 4 This 'invention relates to a locking-apparatus, intended to be placed upon the stile upon the inside of one of the'blinds, andhairing a catch or'hook to catch into a staple, or its equiyalent, attached to the other blind of thesame window.' The invention is intended to provide a secure means of connecting one blind tothe other 'near1 the centre, andto furnish a. fastening wh-ich, while it may be opened readily from the inside by personsV i acquainted with its operation, shall'yet be diiiicult to 4open from the outside, and prevent, 4to'some extent, at

least, its being interfered with byy children.

J t General Description, Afisthe ease oi" ourblind-lok'orffastener, which easemay'be madein the forni represented, or in various Othl bms'wbch arccgminonin the construction of locks. This casing, with the parte it .eontains,lis attached 4tothe stile of gone of the blinds'o'f a window, -and'perhaps, also, -to the 'muntee or cross-piece, as shown' in iig.

p `IB is a spring-catch, intended-to,catclrfintoa ...staple or its equivalent on the adjacent blind. This catch B is hung at one end upon'a pin',:D,' Vand is' thrown into place in the staple by a spring, E, the ends ofwhich are,

kept in position by the pins t andfb. is a. detent, secured at the lower end'to thev case A, and having on itv a. lip, c, for holding the catehj B in en elevated position, so tha-t when freed itfs'hali fall into place in a staple attached 'tothe contiguous blind. Thisfdetent F is made of elastic metal, and thin, so asv to be easily thrown back to allow the catch B to fall into position. G is a key, by which the catch B is raised intol position to operate when the blindsare closed. This key G has'a projection, d, upon it, which catches under theca'tch B to raise it into positiom. It also has anotherprojection, e, upon it, which tits into s. notch in the upper plate of the loekor fastener, and which drops below said plate when the' blinds are closed and fastened, and which, when in that'fposition, may be turned out of line wth the n'otch in the top plate oi'- the lock, and thus rendered more secure from being operatedfroin the outside, and `from the interference of. children, as the projection e must be brought back to e'oincidewith the-notchl in the .plate before the key can be raised so as to release The case A, with the part-s it contains, beingattached to the stile of one ofthe blinds, as shown, a pin, I, is set in the stile .I of the adjacent blind, in such a position-that when the blinds are closed, said pin will "strike the detent'F, and force it back, so as to allow the catch B to fall into thelocking'postition. A. staple,

said staple, and prevent the blindsfron being opened. i

`I t will be seen from this description that the catch B, having been raised by the key G, it will be held in position till the blinds are closed, when the pin I, striking the detcnt F, will force'the latter back and allow the catch B to fall into the stapleK, by which operation the blinds are effectually 'secured from opening until the catchiB is'again raised by means of the key G. It 's obvious that the construction of'the key G maybe modied in various ways andstill be adapted to the purpose, or `instead. of this construction an ordinary' key, suol' K, is alsov attached'to the stile .Linsuch a. position that when the blinds are cl osed,'the catch'B will fall into as commonly used for opening locks, maybe fitted to raise the catch B, though if detachable it must be subject to the objection of liabilityto loss.

Our lock or fastener can also bc so constructed that the detent F shall be thrown back by the staple K, if l desired, but we prefer the construction above described.

C'Zaz'ms.

We claim as our invention- 1.- 'lhe combination, in ablind-lock or fastener, of the catch B and spring-detent F, substantially as and to tbe eiect set forth.

2; The combinationin a blind-lock or fastener, of the catch B, detent F, and key G, substantiallyas set forth.

8. The combination of the catch B, detent F, and staple K, substantially as\herein set forth. 4. The combination of the catch B, detent F, staple K, and pin I, or its equivalent, substantially as heireinabove set forth.
